HORSESHOE-MAKING MACHINE.

Specification of Letters Patent.

Application filed August 10, 1910. Seral No. 576,473.

To all whom 'it 'may concern: Be it known that I, JOHN A. MCLAUGHLIN,citizen of the United States, residing at San Rafael, in the Count-y ofMarin and State of California, have invented new and useful Improvements111 Horseshoe-Makng Machnes, of which the following 1s a specfication.

This invention relates to forming ma-' chines and particularly pertainsto a machine used for the manufacture of horseshoes from blank stock.

The Object of this invention is to provide a powerful, simple andmanually operable machine for the manufacture of horseshoes; to providea machine to be used, and adjusted, to facilitate the manufacture ofhorseshoes of different sizes; to provide means in combination whereby apiece of blank stock may be suitably bent to form the blank shoe, meanswhereby the holes for the reception of the nails may be` -may beremovably secured or integrally formed therewith arched` bearing plates3, between which is a space 4 of suitable Width for the reception andguidance of a bell crank lever 5, pivoted at 6 upon a removable bolt orpivot 7.

Upon the short angular extension or arm of the lever 5 is pivoted, at 8,a ,suitable fullering wheel 9, and adjustably fastened by means ofscrews, bolts or other devices, upon the table 2 and below the wheel 9,is an inclined flanged anvil 10, between which anvil and the roller theshoe is clamped, during the fullering operation, by means of a viselever 11.

Preferably before the shoe is placed upon the anvil 10, it is firstbent, to form the quarter of the shoe, about a fixed die plate 12,removably attached by bolts or screws as at 13, to some convenientportion of the bedplate or table 2 of the machine. One of the edges ofthis die plateis in the form of a conveX curve and which, in coperationwith a swinging lever arm 14: having a concaved complementary face 15,will give to the blank the desired curvature when the blank, which hasbeen previously heated to the desired temperature and is suflicientlyflexible, is' clamped by the arm 1 1 and when this is firmly andpowerfully swung upon the blank to press it against the fixed die plate12. After one side of the shoe has been given a reasonable amount ofcurvature, the blank is turned end for' end and the other side of theshoe formed.

While the partly formed shoe is still in the heated condition it is thentransferred by the operator to the anvil 10 and this is adjusted so asto allow the proper thickness between its inclined face and the movablefullering wheel 9. When the proper adjustment of the anvil has once beenobtained it needs no further change until it is desired to form shoes ofa different size. The shoe,

having been adjusted upon the anvil 10, is

firmly clamped thereon by thejaw of the vise lever 11. The operatorstill holding the shoe firmly in place by means of the handle of thelever 11 at the same time grasps the upper, handled, long arm of thelever 5 and gradually swings it downwardly until the fullering wheel 9engages the face of the inclined shoe and the wheel sweeps firmly andgradually along the upper exposed face of the shoe.

The transverse shape of the fullering wheel 9 is preferably fiat on oneside and is beveled on the opposite side, so that its edge will form agroove, triangular in cross section, on the face of the shoe, thevertical edge of the groove being practically parallel with the verticaladjacent edge of the shoe, and the inclined face of the groove slantingupwardly and outwardly toward the outer edge of the bar of the shoe.This groove is generally known in theart as the fullering in which thenailholes are punched. 4

After the two fullering creases have been made in the heated shoe insuccessive operations, the operator then raises the operating lever 5,lifts the shoe from the anvil 10 and places it upon a perforated die 16adjustably mounted, below the arched bearing 3, upon the bed or table 2of the machine, Verti-' cally movable above this die and guided insuitable bearings in the plates 2 is a punch 17 adapted to be pressed,obliquely downwardly by means of a toggle and lever connection with theoperating lever 5. This toggle and lever connection comprises links 18pivoted at 19 on the lever 5, and at 20 in the upper end of a cam bar 21having formed on its lower end and turnable about the bolt 22 a cam 23bearing upon the T- plate 24: at the upper end of the punch 17.Interposed between this T-plate and the bars of the punch is a suitablespring 25 whereby the punch is normally elevated and the T- plate iskept in contact with the cam 23.

The perforated die is preferably formed with a flange 26, the functionof which is to engage one edge of the shoe as it is placed on the faceof the die and over the perforation, so that the operator may act withrapidity in moving the shoe about the face of the die without fear ofits slipping from side to side and thus causing the nail holes to beimproperly located.

\Vhen a shoe has been placed on the die the lever 5 is then grasped andpulled downward. This will result in the depression of the punch 17 bythe cam 28 and the shoe will be perforated.

It is common in the manufaeture of horseshoes to punch the holes for thenails at a sliglt angle and for that reason I prefer to mount thedetachable and interchangeable punch point 27 at aslight angle whichwill automatically and positively punch the holes at the desired anglewithout any effort on the part of the operator to position the shoe atany peculiar or particular relation on the die.

In order to prolong the wearing quality of the fullering wheel and ofthe punch, I have provided suitable nozzles 28 adjacent and connected toeach, and to these nozzles a supply of cooling fluid, such as water,which may be delivered from any suitable source of supply, valves 29being provided to control the volume of water delivered to' the nozzles,the purpose of the nozzles being to keep the operating fullering wheeland punch from becoming overheated and thus softening and becomingineffective. The manifest advantage in coolingthese tools is that itwill be unnecessary to renew or resharpen them as frequently as theywould have to be if they were not kept cool during the operation. i

A particular feature of the invention is the adjustability andrenewability of the anvil and of providing it with a vertical flange 10for the guidance and support of the shoe. This flange not only serves toform a stop against which the shoe abuts when the operator places it onthe anvil, but it also 'assists the clamping of the shoe by means of thevise lever and supports the exterior edge of the quarter of the shoewhile the fullering operation is being performed.

Having thus described my invention, what I claim and desire to secure byLetters Pat-` ent is- 1. Inahorse-shoe making machine,a fulleringmechanism comprising an inclined fianged anvil, a lever pivoted betweenits ends to form a long and short arm thereon, and a fullering Wheelmounted in the short arm of said lever, and operable over said anvil.
